Abstract
A comparative study on the effect of chemical fertilizers and bio-fertilizers was done on growth and biochemical parameters in tomato plant (Lycopersicum esculentum Mill.). An experiment was conducted in randomized complete blocks design (RCBD) with four replicates. The treatments were (T1= control, T2= bio- fertilizer, T3= chemical and T4= combination treatment (biofertilizer and ½ chemical)) at Agricultural Technical Institute of Bakrajo, Sulaymania, Iraq during 2014. The bio-fertilizer used in this study was phosphate barwar2 and chemical fertilizer was triple super phosphate. The material consisted of one cultivar of tomato localspecies. The results indicated that there were significant difference between the application bio-fertilizer and chemical fertilizer for yield and yield component traits. Comparison means were conducted by Duncan method. This study indicated that a combination treatment of bio-fertilizer and chemical fertilizer had significant effect and increased the yield and growth traits of tomato. Correlation analysis showed that the strongest positive relationship was between fruit yield and total fruit weight per plant (r = 0.78). The results of regression analysis by stepwise method for fruit yield in tomato indicated that total fruit weigh can justify 65.3 percent of the fruit yield variation. According to this study using bio-fertilizers has increased fruit yield and yield component of tomato significantly.
